Thanks!
That's weird error. Try installing latest love2d (use this ppa if you're on ubuntu). Also, assets are stored using Git LFS, make sure you've got them, e.g. execute command
git lfs fetch --all
Got it working! I’ve never worked with git-lfs before :)
sudo apt-get install git-lfs git fetch --all git pull git lfs fetch --all git lfs pull
Yay I'm glad it worked :)
